Very quickly activated

This is only the 2nd month using my unlocked B535-333 4G+/LTE CAT7 mobile router.(https://amzn.eu/d/15hHLOV)The first month a different company supplied the sim. Which was also a 02 sim, and that was okay too. But when the first month was coming to an end the previous company wanted to charge me £5 per month more than what I paid for the 1st month. So I shopped around and got this deal with onecall. If they don’t try and hike their rates I may well stay with them.Popped the sim card into my 4g router, followed the set up instructions that came with it, and onecall activated it very quickly! It was up and running within 30 mins! (Tuesday morning). Very simple and efficient procedure.Tried it at 2 different addresses, 15 miles apart.Address 1, where download speeds weren’t brilliant, but done the job. Was getting between 4mbps and 20mbps. Albeit we were experiencing some bad storms. Never seemed to affect my internet usage including my streaming of now tv. Next morning 5.30am I was getting faster speeds of around 55mbps. But it slowed down again during peak times.Address 2 (and where it will mainly remain for the time being). (Storms had ended by the time it was used at address 2). Speeds were much faster, always between 30mbps and 85mbps.Having experienced no real inconvenience with this sim for 2 weeks now, and the easy no nonsense speedy activation process I give it 5 stars.*Update* 12th March 2024I’ve since had a 2nd sim from onecall via Amazon. Same online set up procedure. Was on a Friday morning. Only took onecall 10 mins this time to activate. Just don’t try and activate at the weekend, as no one’s there it seems.

Well after a blip with signal it's working fine now so not the fault of the SIM 🤔🤗🤗

Good value, High Speed, Exellent support.

This unlimited data card gives good value, not locked into a contract, but at a comparable or cheaper price to a contract.I'm getting speeds of around 30mb, which is of course location coverage dependent, but 10 times faster than my home broadband.Due to what turned out to be my own issue, I contacted support, it was fast, professional and effective (that is a rarity). I only write reviews for exceptional products (good or bad). This has been great.

Worst activation

When I bought this sim card, I felt what people felt in the Stone Age.

O2 is ok ,just.

Price good for 30 days unlimited .I travel a lot to the UK and there I need the internet for browsing and streaming from YouTube and all 4.The deal is good but I struggle with the constant dropping out and slowing down and " doughnutting" whilst trying to browse or watch a film on TV.Doesn't help that I also have a ee card in a separate hotspot and it blazes away all day and night.Only difference is the network provider.

Instant access to broadband

I live in a remote area and have struggled with getting a good signal through broadband for years. But now I have this, it is almost instant and it is making such a difference to me.

throttled to 10MPS and not the top speed it promises to be

speed never went above 10 mps at any time night or day
